To `all whom it may concer-n,.-

Be it known that i-,WILLIAM R. WooD,a citizen of the United States, and a resident of Lewistown, Miiilin county, Pennsylvania,

have invented certain Improvements in Forging Dies, of which the following is a speciication.

The object of my invention is to so construct a die for forging axes as to provide for' readro ily changing he shape of the head or poll of the ax or compensating for excess or deficiency of metal in the head portion of the blank; and these objects I attain in the manner hereinafter set forth, reference being had I 5 to the accompanying drawings, in which- Figure l is 'a sectional View of the upper and lower dies of an aX-forging press, the lower die being constructed in accordance with my invention and-the dies being closed z'o or in the position which they assume whenA Yacting upon the blank.l Fig. 2 is a.F pianr top view of the lower die. Fig. 3 is a perspective View, on a larger scale, of the headblock used in connection vwith said die. Fig. 4. is

' z5 an en d view-of said block, and Figs. Sand 6 are views of dierent .forms of head-blocks which may be substituted for 'that shown in Fie. 2.

ily invention relates to that class of ax- 3o forging dies known as open dies-that is to say, dies in, which the matrices for the reception of the arr-blank extend out to the edges of the dies at the head end-such dies being much more readily made than closed dies, because the head portions of the matrices can be formed by planing or milling instead of by chipping and filing, as is neces ,sary in the case of such closed dies. When such open dies are used, however, a third ele- 4e ment or headblock must be employed for tilling the open ends of the matrices and properly confining and shaping they metal ot the head or poll of the ax, and usually this head block is a piece independent of the dies and 45 carried by a structure beyondthe side ot the press, a plan which is not only expensive,'but

also cumbersome and inconvenient.

In carrying out my invention l. use a headblock which Iis carried by and forms in eect 5o part of the lower die of the press, and I mount said head-block upon said lower die so that it can he readily adjusted thereupon or removed from and replaced thereon, thus pro- -viding a means of compensating for excess in or deficiency of metal in the blanks and also permitting a ready change of head-block when.

a change in the shape oi the head or poll of, the ax is required.

In the drawings, l represents the upper die, which is an open die of the usual character, 6e my invention having no reference thereto. The lower die 2, however, has a longitudinal extension 3, in which is a transverse recess l 4, preferably dovetailed and adapted for the reception of a dovetailed rib 5 upon the under 65 side of the head-block G and also Vfor receiving wedges? and 8, which are interposed between said rib and the walls of the recess 4.

` The head-block 6 lits snugly into the head portions oi the matrices 9 when the two dies 7o p are brought together, and the inner, face of vthe'head-block is shaped so as to conform to the desired configuration of the head or poll of the ax, three dierent shapes of such head clock being shown in the drawings.

It occasionally happens that a run of blanks will exceed slightly the normal weight, in which case the excess of metal must be forced into the head, portion of thoax, andby proper adjustment of the Wedges 7 8 the head-block 8o can be backed oit suiiioiently to accommodate such excess of metal. On the other hand, the blanks sometimes Waste away in the heating process, so that they fail to come up to weight and do not properly lill out in the heads. To compensate for this, the headrblock may be moved inward slightly, as will he readily understood.

By removing the wedges the rib 5 of the head-block can be withdrawn from the recess 9o 4 and another head-block inserted in place of the one removed and then secured in the desired position by reinseriion of the wedges.

4The dies have in addition. to the matrices 9 for the formation of the ax the usual recesses lO for the reception. of the mandrel 11, which passes vthrough the eye of the an and remains therein during the forging or pressing operation.

Having thus described my invention, I roo claim and desire to secure by Letters Pat-A ent- 1. An 1X-forging die-block having an opendy I ended ymatrix and a head-block closing sai open end of the matrix and carried wholly by, but; adjustable upon ,the die-block, so as to project more or less into said open end of the matrix, substantially s specified.

2. An :Lx-forging die-block having an cpenended matrix, and a head-block closing said open end of the matrix,and carried wholly-by, but detachable from the die-block, substantially as specified.

3. An azi-forging die-block having an openended matrix, and a. transverse recess, aheadblock closing said open end of the matrix and havinga rib contained in said trfinsverse recess and means whereby said rib is secured in the recess, substantially as specified.

4. An ax-forgingdie-biock havingan openended matrix, a head-b1ock closing said open end of the matrix and carried wholly by the die-block, said head-block being movaoic so as to project more or less into said open cmi of the matrix, and adjusting devices forsa-i/.l head-block also carried Whoiiy by the die biock, substantially as specified.

In testimony whereof I have signed my lm me to this specification in the presence of subscribing witnesses.
